v Referring now to the embodiment .of the invention illustrated by wayof example in the accompanying drawings, a vertically disposed frame Iis shown, having a base 2, the frame being preferably of integral she etmaterial, as for instance welded sheet steel. The vertically disposedpart of the frame constitutes the back of the machine, and is preferablybox-like and internally hollow, thereby affording support and housingfor the actuating and controlling means. The. upper portion 4 of theframe is curved forwardly to constitute an overhang from which'issupported the upper part of the pressing mechanism, and a 1'5 sittingwith full freedom to-change position as i straight-line mounting isprovided for the pressing mechanism between the head 4 and the base 2 ofthe frame. The front of the machine is entirely open and the pressingmechanism is mounted at the front of the machine.

In accordance with one feature of the invention, one member of thepressing couple is movable laterally to and fro between a Work pressingposition and a work receiving and delivering position, which latterposition is directly in front of the operator and at a substantialdistance from the pressing station. After the operator has positionedthe work, it is carried from the operators station to the pressingstation, and after pressing it is returned to the operators station bythe movement of this part of the machine.

As embodied, one of the pressing members, such as the pressing head I!is mounted or suspended from the head portion 4 of the frame in aforwardly and outwardly inclined position, and

the other member of the pressing couple, such as the buck I2, is mountedto swing on a pivotal support, inwardly into pressing position inalinement with the pressing head (solid lines, Fig. 2) and outwardlyaway from the pressing position, past its vertical center, into anoutwardly and downwardly inclined work delivering and receiving position(shown in dotted lines in Fig. 2). As shown, the pressing buck I2 ismounted upon a support l3, which at its bottom end hasdownwardly-projecting, apertured lugs I4, which are pivotally supportedupon a shaft 5, which is mounted in brackets l6 and H, fixed to andextending upwardly from the base 2 of the frame. The work support thushas an ample pivotal bearing directly on the machine frame and directlyin the line of thrust of the press, and the cooperating presser head isstationary except for the free, straight-line movement to effect thework pressure between the head and the buck. The members I! and I2 ofthe pressing couple are disposed in inclined position for the pressingaction, the entire structure being inclined inwardly and upwardlybetween the base 2 and the head 4- of the frame, and the ironingpressure is exerted only in the direct longitudinal line of the parts,and also is exerted directly on the presser members, without the use oflevers or like mechanisms.

The buck I2 and its pivotally mounted support I3, after the pressing iscompleted, are caused to swing outwardly from the full line position tothe dotted line position of Fig. 2. In this dotted line position, thebuck is inclined forwardly and downwardly directly in front of theoperator in the most favorable position for rapid and efficient removalof the finished work and for like loading of new work on to the buck.The work is thuspresented directly to the operator at a fixed station,who may be sitting or standing, and the forwardly inclined position ofthe buck is most favorable to rapid and efficient handling of the work.The upwardly and outwardly inclined support permits space for theoperators feet beneath the support in the open position, so that thework is brought within easy and eflicient reach of the operator, in aseated position. The inclined positions of the presser members also givevery effective drainage of condensed steam from the heating system. Atable l8 may be provided on the support l3 if desired.

Referring now to the embodied form of means for actuating the travelingbuck and its support (Figs. 2, 3 and 5), it is designed to be operatedby pressure fluid, such as compressed air, and in said form a cylinder2! is pivotally supported at 22 upon the frame of the machine. Thecylinder has a double-acting piston, and its piston rod 23 is pivoted at24. to the supporting pedestal l3 of the work carrier. The fluidpressure is applied alternately at the two ends of the cylinder 2| toswing the carrier to and fro between the pressing position and thework-receiving and delivering position at the will of the operator. Themechanism for operating and controlling a single press is shownespecially in Figs. 2 and 3, and will be first described, and asembodied the compressed air is brought from a suitable source by a pipe21, which communicates by a short pipe 28 with a valve 29. Valve 29 isconnected to the right-hand end of cylinder 2| to apply the air pressureto swing the pedestal it from the workreceiving position, shown indotted lines in Fig. 2, to the work pressing position, shown in solidlines in Fig. 2.

A pipe 32 connects with the valve 29 and by a flexible pipe 33, whichopens into the right-hand end of the pivoted cylinder 2|. The valve 29is constructed to normally connect its end of cylinder 2| to theatmosphere while cutting off the pressure from pipe 21, and is then inthe position of the valve 29 in Fig. 5. Pedal-operated means arepreferably provided whereby the o erator actuates valve 29 to swing thework pedestal from the dotted line to the full line posi tion of Fig. 2,and as embodied a spring-pressed foot pedal 31 is pivoted at 38 upon themachine frame, and has a downwardly-extending arm 39 adapted to contactwith the end of the valve stem 40 of valve 29, which projects from thevalve casing. The stem 4B of valve 29 (Fig. 5) has fixed thereon twovalve discs 3-5 and 46, which are located in valve chambers 3 and 4 5,respectively. There is an air port ll communicating between the twochambers, and a spring 48 urges the valve 45 onto its seat to normallyshut off the pressure from the pipe 2'5, and the spring holds valve disc46 open, and pipe 32 and chamber 44, and the right-hand end of cylinder2|, are normally in communication with the atmosphere.

When the pedal 31 is depressed, valve stem 40 is moved against itsspring 68, valve disc 46 is closed, and disc 45 is opened against thespring, and the air pressure from pipe 27 passes through pipe 32 intocylinder 2| and moves the piston to the left, and swings the pedestal itfrom the dotted-dine work-receiving position to the fullline pressingposition in Fig. 2. Fne pedestal comes to rest against a suitable stop,with the pressing buck l2 in alinement with the pressing head II and isheld in that position by gravity, and the air pressure is cut off fromcylinder 2| by the operator releasing the pedal 3'1, which cuts off theair pipe 21 from the cylinder, and relieves the cylinder and pipe 32into the atmosphere.

There is provided by one feature of the invention a presser head mounteddirectly upon the machine frame, and having no other necessary movementexcept the relatively short, straightline movement required for exertingthe pressure upon the work, and this movement is of variable extent,automatically accommodating itself to variations in thickness of thework or of the padding, and thus the full predetermined pressure isexerted on the work under these varying conditions. As embodied, thefluid pressure operates directly upon the presser head at a plurality oflongitudinally spaced-apart points with floating pressure, which insuresuniform pressure throughout the work, applied directly, and without theintervention of levers or other connections. As embodied, theelongatedpresser head II has projecting from the upper face thereoftransverselyedisposed pairs 'of-upwardly projecting rods 54, 55 and 56,51, the respective pairs being spaced apart along the head. These rodsare resiliently supported thereby to hold-the presser head I Iyieldingly away from the pressing position, while allowing the airpressure to act directly upon the head ll at these spaced-apart pointsto press the head against the work; As embodied, two diaphragm chambers58 and 59 arefixed at 60 and 6| to the head A of the machine frame andextend downwardly therefrom. The diaphragm casings 58 and 59 have,respectively, downwardly-extending cylindrical portions 62 and 63, whichterminate in transversely disposed plates 64 and 65.

The pairs of rods 54, 55 and 56, 51, which extend upwardly from the backof the presser head II project through openings in these plates 64 and65, respectively, and coil springs 69 and I reston the upper faces onthe plates 64 and 65 and are in compression between the plates and nutsII and I2, screwthreaded onto the upper ends'of the rods, the presserhead II thereby being supported resiliently away from the work position.7

In the embodied means whereby the fluid pressure moves the presser headI I against the action of the springs 69 and I0 and presses it againstthe work on the buck I2, there is mounted in each of the cylinders 58and 59a diaphragm I6, and within said cylinders and on the under side ofdiaphragm I6 is a loose piston 11, having a central boss I8 to which isfixed a rod I9. The rods I9 project downwardly, respectively, throughthe hollow cylindrical extension 52 or 63, and these rods I9 haverounded outer ends that fit into cup-like sockets in the back of thepresser head i I. The fluid pressure is admitted to each of thecylinders 58 and 59, and the pressure is thus applied independently attwo spaced-apart points along the resiliently-supported presser head II, thereby causing the pressureto be applied conformably and with equalforce to all parts of the work, I

Means are provided whereby the ironing pressure against the work isinitiated and maintained automatically when the work support reaches thepressing position, and is then maintained automatically, either for apredetermined timeor at the will of the operator. In said embodied form,a valve mechanism is provided which is actuated by the pedestal I3coming to rest in the pressing position, the valve mechanism turning theair pressure into both diaphragm cylinders 58 and 59, the pressurethereafter being maintained on the work, either until the operator isready to move the pedestal to delivery position, or after apredetermined time period, as hereinafter described. In the embodiedform of valve mechanism, which is shown of somewhat diagram matic formfor the sake of clearness (Fig. a

contact lug 99 on the pedestal I3 engages with the stem 99 of adouble-disc valve mechanism 9I when in the pressing position, as shownin Fig. 3, and at the left in Fig. 5.

Valve 9| receives the compressed air from a pipe 92, which branches offfrom pipe 32. The valve is normally held with its disc 94 seated anditsdisc 95 open by a compression spring 96. The valve has a central port91 communicating by a pipe 98 with a cylinder 99 in which works a pistonI00. The piston 100 has a short piston rod which bears onone end of alever IOI', which is pivotallysupported at I02. On the opposite side ofits same end lever IOI bears on the valve stem I04 of a double-discvalve I05 similar to the valves already described. Valve I05 is normallyheld by a spring I06 with its lowermost disc seated, thereby to shut offthe fluid pressure from the cylinders 58 and 59. The valve mechanismcomprises also, as a holding. device for valve I05, a cylinder I09 inwhich works a piston IIO, having a short piston rod which bears againstthe under side of lever IOI at its opposite end. 'A pressure supply pipeIII communicates from the pipe 2'1 to the chamber of valve I05. A pipeII2 leads from valve I05 and supplies the fluid pressureconcurrently toboth of the actuating cylinders .58 and 59 of the header II. A pipe H3communicates from the cylinder I59 to release the pressure in cylinders58 and 59 and to permit the springs 69 and Illto lift the pressing headI I from the work after the pressing is done.

Themanner of operation of this valve mechanism is as follows: When lug89 moves valve stem 90 against spring 95, the fluid pressure from pipe92 is admitted into cylinder 99, and piston I00 is moved downwardly, andthereby opens valve I05 against the pressure of its spring I06, and thefluid pressure passes from pipe III through pipe I I2 into each of thecylinders 58 and 59, onto the diaphragms I5 and their pistons 11,

forcing the presser head I I upon the work carried on the buck I2, andat the same time compressing the springs 59. and "I0. Concurrently thepressure fluid enters cylinder I09 forcing piston H0 upwardly, and leverWI is thus held in open-valve position by the air pressure under pistonH0, and with the'fluid pressure maintained on the presserhead I I. Thispressure will be maintained until relief of the cylinder I99, either bya relief mechanism operated by the operator in actuating the mechanismfor swinging the support I3 back to the work-delivery position, or bythe operation of a time mechanism. Any known or suitable means may beemployed, if necessary or desirable, for effecting the timing of theparts so that the: pressing action will not begin until the work supportis in position. Also, any suitable means may be employed ior heating thepressing members II and I2.

Referring now to the embodied means for moving the work support back todelivery position in front of the operator, a valve mechanism H6, whichmay be the same or similar to the valve mechanism 29, is connected by apressure supply pipe II? with the pipe TI. This valve, as stated, is ofthe same double disc type and is springheld-to shut off the fluidpressure from cylinder 2I. A spring-pressed pedal I29 is pivotallymounted at IZI upon the machine, and has an arm I22 engaging with alongitudinally-slidable rod I23, which when the pedal I20 is actuatedagainst'its spring engages the stem 524 of the valve M5 to open itagainst its spring. A pipe I25 communicates between the valve H5 and theopposite end of cylinder 2! by means of the flexible hose I25. Whenpedal I29 opens valve H5, the fluid pressure is admitted to the lefthandend of cylinder 2i (Fig. 3), and the work support I3 isswung from thepressing position to the work delivery position, which latter is shownindotted lines in Fig. 2. The work support I3 need be moved only over itsvertical center by the cylinder 2 I, and then will move by gravity andcome to rest inthe work-delivery position 76 against a suitable stop,not shown, and the pressure in the cylinder 2| can be immediatelyrelieved.

The embodied means for moving the presser head I I away from the work,preparatory to this return movement of the work support, comprises adevice for relieving the pressure on the piston I III, which is operatedby the pedal I29, the parts being so timed that the head II is free fromthe work before the return movement begins. As embodied, a relief valveI2? is provided for the pipe H3, and this valve is actuated by a leverI28, which straddles the rod I23, and in engagement with a collar I29fixed on the rod, and when lever I29 is depressed lever I28 is moved toopen valve I21 to release the pressure. Thereupon piston IIIl drops, andspring I05 closes the valve I95, and the pressure in pipe H2 is relievedthrough pipe II3 and valve I21, and springs 59 and I act to lift thepresser head II,

In accordance with one feature of the invention, two pressing mechanismsare interconnected to be served by one operator from a single workposition or station, means being provided Whereby the operator servesand controls both pressing mechanisms and operates them concurrently inreverse directions. Thus after the work is put on one pressingmechanism, the work support moves to the pressing position andconcurrently therewith the work support of the other pressing mechanismmoves in the opposite direction, and brings the pressed work in positionbefore the operator to be taken off and for new work to be placed on thesupport. Thereupon the mechanism is again operated to carry the newplaced work to the pressing position, and to move the pressed work onthe other pressing mechanism into position before the operator ready tobe taken off. This machine is shown in plan in Fig. 4 with the twomechanisms arranged at rightangles to each other, the operators positionbeing indicated by I33. It will be noted that the work supports in theopen position occupy in part the same space, due to both machinesdelivering the work in front of the operator, but there is no mechanicalinterference for the reason that one support is moving toward pressingposition while the other support is moving toward delivery position.

The interconnections whereby the two machines are operated insynchronism are shown diagrammatically in Fig. 5, and in many respectsthey are the same as the actuating and controlling mechanism for thesingle machine already described, and only the differences inarrangement need be further explained. The main differences are that themechanism on one machine for lifting presser head II away from thepressed work, and for moving the work support back to delivery positionbefore the operator, is here controlled automatically by the mechanismon the other machine which the operator actuates to carry the work tothe pressing position. Thus when the operator has completed the work onone mechanism, and starts the work toward pressing position, thisautomatically carries the pressed work on the other machine away fromthe pressing position and places it before the operator, ready to betaken off.

In this double machine, therefore, the valve 29 on either machine, whichmoves the work support to pressing position, is also connected throughpipe 32 to pipe I25 which supplies fluid pressure to the opposite end ofcylinder III of the other machine. The valve 29, when actuated, therebymoves its own work support to pressing position, and at the same timesupplies fluid pressure through pipe I25 into cylinder 2| of the othermachine, and moves the work support of that machine from the pressingposition to the delivery position in front of the operator. In likemanner the preliminary retraction of the presser head II from the workis effected by connecting the relief pipe I I3 and valve I2I to beactuated concurrently with the opening of valve 29. For this purpose therelief valve I2'I' is connected to be operated by a longitudinallyslidable rod I35, which in this instance is interposed between theactuating lug 39 of the foot lever 31 and the stem 40 of valve 29, andthereby the one pedal is employed to operate in unison the mechanism formoving the work support of one machine to pressing position and the worksupport of the other machine to the workdelivering position.

In accordance with one feature of the invention, means are providedwhereby the pressure upon the work may be terminated after a settable orpredetermined time, so as to guard against overheating of the work or ofthe presser pads. This mechanism is arranged to release the pressure offthe work independently of the operation of the lifting mechanism,previously described, which operates automatically when the operatormoves the work support back to delivery position. This mechanism has oneof its main uses in guarding against overheating in one of the pressermechanisms of the double machine in case the operator is delayed inarranging the work on one machine and starting the return movement,although it will operate equally well on a single machine. As embodied(Fig. 7), a rod I49 is pivoted at I4I to the swingable work-supportingpedestal I3, the rod being pivoted at its other end I42 to a bell cranklever I43 pivotally supported at I44 upon the frame I. The other arm ofbell crank lever I42 straddles a longitudinally movable rod I45, andbears against a collar I45. Rod I45 is reciprocable in a guide I41 andis pivoted at its other end I48 to the piston of a dash pot timer I49having a small port 10 near its lower end and beneath the piston. Arelief valve I56 which is part of time mechanism I59 (Fig. is connectedby a pipe I5I to the relief pipe H3 and has an actuating lever I52 inthe path of a collar I53 fixed on rod I45. When the press is opened,lever I43 is swung to the dotted line positionv and lifts rod I45 bymeans of collar I46. When the press is closed, and the pressure isautomatically applied to head II, lever I43 swings back to the full lineposition of Fig. 7.

However, the dash pot maintains rod I45 in the elevated position, and itmoves down only very slowly under control of dash pot I49, the dash potemitting the air beneath its piston sufficiently slowly to effect thedesired time delay in easing the ironing pressure. After thepredetermined time, rod I45 has moved downwardly sufliciently for collarI53 to engage the valve tripping lever I52, and valve I56 relieves thepressure in pipe H2 and springs 59 and I9 lift the presser head II,which thus occurs after the predetermined lapse of time allowed for thepressing.

A different form of valve mechanism for holding the presser headpressure on the work and for releasing it is shown in Fig. 6. In thisform a double-disc, spring-pressed valve I53, of the type previouslydescribed, is interposed between the constant pressure pipe III and thepipe I I2 which supplies the fluid pressure to the cylinders '58-" andtand from-"them tic presser head I'I. position in'front er the-operator,and means The pipe 92 to which pressure is admitted by the valve 2 9,-communicates with acylmder I I54, having a piston I55 which'is, impelledtoward the top of the cylinder bya spring I56.-' The piston rod ofpiston- I55 carries at its end an interponent I51. A bell-crank leverI59 is pivoted at" I60, and one end of the lever is adaptedto coast thevalve stem of valve I53, the other end of bell-crank lever I59 coactswith the piston rod I62 of a piston I63, which works acylinder I64,whicnacts as a holding device for valve I53. A pipe I65 communicatesbetween valve I53 and the lower end of cylinder I54, and

the relief pipe II3 opens out of the bottom end of the cylinder.When-thevalve 29 is opened by the operator, to bring the Work Support topressing position, the pressure inf-pipe 92 moves piston'l55 against itsspring and moves-interponent I51 into position to be engaged by lug 89when the work support comes to pressing position. This rocks bell-crankl'ever I59 and adhits the fluid pressure from pipe II'I into pipe H2 andputs the pressure on the head I I. When the operator releases valve 29after thework support has swung over its center, spring I56 retractsinterponent I57, so' that lug 89 no longer holds valve I53 open.However, when valve I53 is opened, the fluid pressure entered the bottomof cylinder ltd, forcing piston I63 upwardly, and piston rod i62continues to hold valve I53 open through bell-crank lever- I59. ValveI53 will be held open, and thus maintain the pressure on head H, untilthe pressure is relievedpin pipe H3, at which time the spring in valveI53 will move the valve to cut off the pressure from head I- l- I andrelieve pipe IIZ into pipe II 3, thereby permitting the springs 69 and10 to lift the presser head II.
